Rich - how is the blog coming?
I think too many Realtors focus way too much on design when the important thing is the content you put on the blog. (you can have the most beautiful blog in the world, but it won't rank for squat if you don't have good content on it.) I know a lot of top bloggers, and their sites are very "plain vanilla", but they get TONS of traffic because the search engines like them, and their readers keep coming back to read their stuff.
Try this:
Write a post about a neighborhood or subdivision in your area. Then, write a "how to" article and post it on ezinearticles.com or articlealley.com. In the Author bio, include a link back to that specific article (with the name of the subdivision included in the text of the link). (This is called a deep-link.)
Assuming it's not a competitively pursued neighborhood, you'll likely make the first page of Google within a week or two.
